BNA's Health Care Policy Report
Programs to rate, grade, rank, or tier physicians based on quality or other measures are becoming more commonplace as the demand for greater transparency and accountability in the nation’s health care system intensifies. For many years, the preferred provider organization (PPO) reflected the most basic form of tiering—physicians were either included or excluded from the PPO network. However, this approach has become more refined as the tools for evaluating physician performance have evolved.
